Musculoskeletal issues like a traumatic injury, osteoporosis, and osteoarthritis are some of the significant causes of disability worldwide and thus an essential branch of public health.
FREMONT, CA: Biomechanics has been regarded to play a vital role in musculoskeletal pathology, treatment, and rehabilitation. Biomechanical factors have the power to influence a cell's metabolic activity, bone remodeling, and sequelae development. The advancement in biomechanical theory, methodology, and technique can promote designing protective, surgical, and rehabilitation equipment. Progress in the computational approach also promoted the development of computational biomechanics.
This special issue focuses on innovative theory and application of biomechanics to understand musculoskeletal pathology and enhance the techniques for the treatment and rehabilitation. This special issue can act as a platform for biomechanical researchers, rehabilitation therapists, protective device designers, and orthopedic surgeons.
Finite element (FE) analysis is a robust tool for biomechanical investigations, specifically in orthopedic surgery. The two independent research groups constructed two separate three-dimensional FE models of the lumbar spine.
The mechanism and protection of sports injury is another focus of this particular issue. A researcher provided two articles. R. Xia et al. set on fatigue's effects on the impact forces and sagittal plane kinematics of recreational athletes' lower extremities in a drop-landing task. They also studied joint torque and mechanical power of lower extremities and its relevance to hamstring strain during sprint running. A group of researchers determined the contact force loading associated with varied walking speeds.
Biomechanics is also popular in rehabilitation in recent years. X. Wu et al. studied early spatiotemporal patterns and knee kinematics during level walking in individuals following total knee arthroplasty (TKA). An article contributed by a few authors studied the effects of overweight and obesity on TKA. Y.-P. Huang et al. investigated arch support insoles' effect on uphill and downhill walking of persons with flatfoot. S. Kuai et al. examined the compensatory response of seventeen major muscle groups' muscle activities in the spinal region, intradiscal forces of the five lumbar motion segment units.
This special issue also included cell biomechanics and other topics. This special issue engulfs a wide range of biomechanics in musculoskeletal health. More research is needed to investigate further in computational modeling in bones, sports injury prevention, rehabilitation, and cellular level to advance the field of biomechanics.
